I was bad - i broke company protocol
Probably the worst thing, was when i was involved with someone who got me a job at an architectural firm. We broke up about a year after and i was distraught. I wanted to know why my now ex-girlfriend wanted to end it. I figured out her email password and for about a week, i was reading her emails at work. Unfortunately, she deleted everything she sent, and the only emails i could read were what was sent to her (the remainder of her previous email was in the email).

Sadly not much was gleened, but it was a sobering experience into a mind that was totally wrecked (mine).
